Definitions

  • a cover member or sheet is then welded to the flattened upper surfaces of the semispherical projections.
  • the panels are filled with lightweight concrete material or the like. However, such panels can also be used without such filling material.
  • FIG. 1 is a perspective view of a panel incorporating this invention
  • FIG. 2 is a plan view of the base member of a preferred embodiment of this invention, illustrating the arrangement of the projections formed therein;
  • Each of the compound projections 16 includes a lower truncated pyramid portion 17 which extend from a plane 18 extending along the lower side of the panel to an intermediate plane 19. Extending from the intermediate plane 19, each compound projection provides four symmetrically arranged, generally semispherical projection portions 21. Each of these semispherical projection portions 21 provides a flattened upper extremity 22 which is coplanar with the flattened surfaces of the other semispherical projection portions.
  • the cover sheet 11, which is a planar member, is welded to each of the flattened extremities 22 by welds 23 so as to produce a unitary structure.
  • the rows of projections are spaced inwardly from the side edges of the panel to provide a peripheral wall 24 joining the outermost compound projections 16 to an upstanding side wall 26.
  • Such peripheral wall extends along the plane 18 and is spaced from the upper cover sheet 11 by the full depth of the panel.
  • the upper extremity of the side wall 26 is bent at right angles to provide a peripheral flange 27 engaging the lower side of the cover sheet 11 and welded thereto by the weld 13.
  • the material of the upper surface 33 of each truncated pyramid which is substantially unworked during the first drawing operation is subsequently drawn in dies to form the substantially semispherical projecting portions 21 in this illustrated embodiment.
  • the depth of the second drawing operation used to form the generally spherical projections 21 is relatively small.
  • the spherical projections have a total height of only 1/2 inch.
  • the total height of the compound projections 16 is 11/4 inches. Therefore, relatively high projections are produced without subjecting the material of the base sheet to deep drawing operations. Because the metal which is drawn during the second operation is substantially unworked during the first drawing operation, the second drawing operation is performed on substantially virgin material which has not been previously work-hardened.
